Leg length discrepancy occurs when one leg is slightly longer than the other. Small differences in leg length are common and often cause no symptoms, but larger discrepancies may affect walking mechanics and place uneven stress on the feet, knees, hips, or lower back.
Over time, these imbalances may contribute to discomfort or changes in posture.
Our foot clinic provides professional leg length discrepancy assessment in Toronto focused on identifying alignment differences and improving balance during walking.
Leg length discrepancy refers to a difference in the length of the two legs. This difference may involve the bones themselves or may occur due to changes in posture or joint alignment.
When one leg is longer, the body may compensate by adjusting posture, which can affect how weight is distributed through the feet and lower limbs.
Common causes include:
Natural variations in bone length
Previous fractures or injuries
Hip, knee, or ankle joint changes
Muscle imbalance or pelvic tilt
Structural differences present since childhood
In some cases, the difference may be structural (true difference in bone length) or functional (caused by posture or joint alignment).
You may notice:
One hip appearing higher than the other
Uneven shoulder or pelvic alignment
Foot, knee, or hip pain during activity
Lower back discomfort
Uneven shoe wear patterns
A feeling of imbalance while standing or walking
Symptoms may develop gradually over time.
Treatment focuses on improving alignment and reducing strain on the body.
Comprehensive biomechanical assessment evaluates leg length, posture, gait mechanics, and joint alignment.
Custom orthotics or heel lifts may be recommended to help balance leg length differences and improve walking mechanics.
Footwear recommendations may help support proper alignment during daily activities.
Stretching and strengthening guidance may be provided to address muscle imbalances contributing to functional discrepancies.
Referral coordination for imaging or specialist evaluation may be recommended when further investigation is necessary.
Treatment plans are individualized depending on the severity and underlying cause.
Consider booking an assessment if:
You experience persistent foot, knee, hip, or lower back pain
One leg feels longer than the other when standing or walking
You notice uneven posture or gait changes
Shoe wear patterns differ between feet
Early assessment can help identify alignment issues and prevent ongoing strain.
If you suspect a leg length difference or are experiencing related discomfort, a professional assessment can help determine whether leg length discrepancy is contributing to your symptoms.
